President Donald Trump is slated to hand over control of the White House to President-elect Joe Biden in three days.
The House of Representatives voted to impeach Trump last Wednesday on an article for "incitement of insurrection" for his role in the Jan. 6 attack on the U.S. Capitol -- making him the only president to be impeached twice.
Here is how the scene is unfolding. All times Eastern.

Republican governor who faced Trump's wrath to attend Biden inauguration
Arizona Gov. Doug Ducey, a Republican, has announced he will attend Biden’s inauguration after weeks of attacks from Trump for signing the certification of Arizona's election results affirming Biden's narrow win in the state.
“It doesn't matter who you supported in the election — once the election is over, we put country before party. Never has it been more important than right now to observe these traditions for the whole world to see," Ducey said in a statement Thursday.
"I was honored to represent Arizona at the inauguration of President Trump in 2017, and I am honored to represent our state at the 59th Inaugural Ceremonies next week. President-elect Biden is assuming office at a critical time in our nation’s history, and I wish him well," he added.
The Arizona Republican Party is scheduled to meet a few days later on Jan. 23, when members will vote on censuring some apparent party foes including Ducey, Cindy McCain and former Sen. Jeff Flake, R-Ariz.

Overview: Trump faces 2nd impeachment trial, Biden assumes office in less than a week
On one side of Pennsylvania Avenue in Washington, D.C., President Trump -- now the only president in history to be impeached twice -- faces another Senate trial following the House charging him Wednesday with one article of impeachment for "incitement of insurrection." Shortly after 10 Republicans sided with Democrats for the vote, Trump released a video from the Oval Office condemning the violence at last week's Capitol riot, which he called a "calamity," but he did not address impeachment.

On the other side of Pennsylvania Avenue stands what's now become a crime scene -- the U.S. Capitol complex. By this weekend, up to 20,000 National Guard troops, many armed, will be deployed to the area amid heightened security concerns and ahead of Biden’s inauguration. Inside the Capitol, metal detectors were installed to enter House chamber earlier this week, and House Speaker Nancy Pelosi announced plans to fine members who don't comply with the new protocol up to $5,000.

Senate Majority Leader Mitch McConnell signaled Wednesday that Trump's Senate trial should take place after Trump leaves office, saying he wouldn't call back the Senate ahead of its Jan. 19 return. McConnell also indicated Wednesday he's considering voting to convict the president, issuing a statement that says he has "not made a final decision." Pelosi has not publicly announced her timeline, but a source involved with deliberations told ABC News Wednesday she plans to send the article to the Senate next week.

Biden, reacting to Trump’s second impeachment late Wednesday, expressed his hope that the Senate will be able to maintain a bifurcated schedule, allowing the trial to move forward along with his agenda -- a message his transition has been consistent on this week. But Democrats are facing the reality that Trump is still likely to loom large over Biden's first days in office.
On Thursday evening, Biden is slated to deliver remarks on the public health and economic crises from Wilmington, Delaware, and introduce his COVID-19 vaccine and economic relief proposal. Vice President-elect Kamala Harris is expected to join.

Trump defense team uncertain ahead of Senate trial
With Trump facing a Senate trial as soon as next week, he has no organized defense team as his top lawyers have refused to represent him.
White House counsel Pat Cipollone, his deputies, and outside lawyers Jay Sekulow, and Jane and Marty Raskin are not expected to be involved.
Trump has been increasingly irritated with his personal attorney Rudy Giuliani and hasn’t been taking his calls, according to sources familiar with the matter, though Giuliani has been spotted in the West Wing recently.

And former Harvard professor Alan Dershowitz is not on board yet, though aides to the president have had discussion with him about joining the team.
Another attorney, John Eastman, whose extremist positions have troubled some members of the president’s legal team recently, is expected to take some sort of role in Trump’s impeachment defense.
Eastman represented the president in the Texas dispute and has previously pushed a racist conspiracy theory about Vice President-elect Kamala Harris.
Trump has asked top aides about how a Senate trial would look this time around. As he did during his first impeachment, Trump raised the idea of testifying himself, which aides dissuaded him from pursuing.

Lady Gaga, Jennifer Lopez to perform at Biden’s inauguration
Lady Gaga and Jennifer Lopez will lend their voices to Biden's inauguration next week, performing when he officially becomes the 46th president of the United States, Biden's Presidential Inaugural Committee announced Thursday morning.
The announcement detailing participants in the 59th inaugural swearing-in ceremony represents one of the more traditional aspects of Biden's inauguration, which has been largely altered amid the COVID-19 pandemic to accommodate an at-home audience, and facing new concerns over security in the wake of a riot at the Capitol last week that left five dead.

Gaga, who appeared on the campaign trail with Biden during the 2020 election and worked with the then-vice president on his "It's on Us" campaign to combat campus sexual assault, will perform the national anthem when Biden is sworn in, the committee announced.
Lopez, who endorsed Biden, and took part in a virtual chat with the president-elect during the campaign, is also slated to perform at the event.
